The above answers are all correct and insightful. But I'd like to add that there's a bit of a difference between 'take effect' and 'go into effect.' The latter typically refers to something that will happen in the future. For example; 'These changes will go into effect on May 17th.' However, 'take effect' can also be used here. But there are certain instances where 'take effect' sounds more natural. For example, if you're taking a sleeping pill tonight but it hasn't started working yet, you would say it hasn't taken effect yet. 'Go into effect' seems to be used more to refer to new sets of rules or standards or changes to something. I don't think I've ever heard or used 'come into effect.'

Bonjour! Je m’appelle Cher et j’apprends français pendant depuis un mois. Je veux l’apprendre parce que je m’intéresse à la culture française m’intéresse. Alors Maintenant, je dois m’entraîner a parler  la langue française. 

Hi! My name is Cher and I’ve been learning French for a month. I want to learn it because I’m interested in the French culture. Now, I have to practice speaking French.

I'm back.... I will be active as of today.

I signed up here a few months ago but I have not been active.
Now I will be active here coz I am eager to learn and practice the English language.
Hope to find friends to practice with. :)

The second would be correct. As you said, 'bread' is uncountable, so 'breads' sounds unnatural. Slices or loaves of bread makes much more sense. :-)

Hello again. :-) 2:17 How does the finance function, in your view, drive that growth both at the top line and at the profit end? 2:28 We are in the unique position that we're (I can't understand the word here either) ... allows us to retain 80% of the money that we make. That means that the more profitable we are, the more money we have for growth. And there's a multiplier effect in that, so if we make a billion-dollar or more advance the next profit, we have 80% of that billing to invest. (I'm almost certain this is what he's saying. He seems to have a slight accent of some kind which is throwing me off.) 2:49 But more importantly, we're more profitable therefore we can increase our (I can't understand the word here) ... we could borrow more money. 3:00 A key enabler to faster growth is drive more, uh, better returns Sorry I failed to pick up some of what he was saying, and English is my native language! I hope this helps.
